IMPROVED BRICK MACHINE.

TO WHOM 1T MAY CONGERN:

Be it known that we, ANTHONY NULSEN, EUGEN HAUEISEN, and ALBERT WAGNER, all of Cincinnati, Hamilton county, Ohio, have invented a new and useful Brick Machine; and we do hereby declarethe following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings making part of this specification. This invention relates to an automatic machine for the manufacture of building bricks, paving tiles, dtc., out of crude clay, direct from the bank.

Figure 1 is a perspective view of a machine embodying our inventions.

Figure 2 is a transverse section thereof.

Figure 3 is a longitudinal section of the moulding mechanism proper.

Figure 4 is a perspective view of the same. I

A suitable frame, A, supports at its upper part a hopper, B, for the reception of the crude clay; the hopper has at one side, near its bottom, aventage, guarded by two rollers, C D, which are propelled in direction of the arrows, in manner hereinafter explained. The bottom B of the hopper supports an endless apron, E, which being stretched around the roller D, and an idler, F, travels constantly as per arrow, carrying along with it portions of clay, which being compressed between and carried forward by the rollers Cand D, reaches a throat, H, where it is pared OH`into thin shavings by the action of a rapidly reoiprocated knife, G, which is guided in a vertical path, so as to closely hug the throat, by means of slots I I in the frame. The rotation of rollers D and C is eiected by wrists, g, of the knife-striking pawls J J, which engage in oog-wheels K K on the ends of the rollers; and the amount of rotation is regulated by the adjustable stops L L', which being setup or down, determine the length of the stroke of the pawls and consequently the feed of the apron E. The knife Gr is reciprocated by a pitman, M, from the shaft n, of one of two rollers N N to whiclrthe clay is conducted by a chute, P, and by which it is a second time compressed, and from which it drops into a converging trunk formed by two endless aprons, Q Q', which are stretched respectively around the upper rollers R R', and the lower rollers R R, and are supported between the upper and lower rollers by back-boards, S S. As the body of clay descends, it becomes still further compacted by the converging sides of the trunk, and at the bottom thereof` enters a separating and conducting throat composed of a rectangular frame or box, T, traversed by a series of equidistant partitions, U, having sharp upper edges, u. The spaces between the partitions Uagree precisely with the desired widths of the bricks. V is the main driving-shaft, having a spur-Wheel, W, which, gearing into a pinion, X, on the shaft of the roller N, effects the rotation of the latter. Y Y are prismatic pulleys, around which is stretched an endless carrier coinposcd of slats, Z, hinged, a, to each other, and whose upper portion is supported on rollers, 1. A suitable number of equidistant slats are provided with followers, 2, which serve to receive and hold the moulds, 3, and compel their advance simultaneously with said carrier and with notches, 4, which receive the points of two reciprocating hooks or claws, 5, that are pivoted to levers, 6, whose upper ends terminate in yokcs, 7, that being vibrated by a wrist or arm, 8, upon te main driving-shaft, cause, through the instrumentality of said claws, an intermittent advance of the endless carrier and its burden of moulds. 9 is a knife, confined to a horizontal path, in close proximity to the under side of the conducting and separating throat by means of horizontal slots, 10, in the frame which receive prolongations from the ends ofthe knife. The knife is rcciproeated by lover 11, whose yoke, 12, is operated upon by a wrist or arm, 13, on the main shaft. The parts above described are so arranged and connected that the carrier, by successive intermittent motions, advances one mould at a time under the conducting and separating throat, and rests long enough for the knife to come forward and sever the clay that is in the mould from that which is in the conducting and separating throat. Thclknife then remains at rest until the next advance of the carrier passes the loaded mould forward, and simultaneously therewith brings an empty mould beneath the conducting and separating throat, when, the knife receding, allows the clay to descend as before. Each loaded mould, as it reaches the end of the carrier, is taken off by an attendant and emptied for return to the carrier. Among a number of decided advantages of this improvement, the following maybe cited: The clay is, by means of thejoint action of the crushing rollers and the shaving-knife, so reduced and comminuted as to destroy the granulation and to reduce it to a homogeneons mass-or paste, the rollers even acting to crush and to reduce to powder any fragments of limestone 0r other rock, so as to prevent their interference with the efficacy of the machine4 then necessary, the clay may beslight'ly moistened before being operated upon. We do not propose to restrict ourselves to the exact form selected for illustration, as the same may be modified in various ways; for example, the hook 5 may be duplicated,` so as to push as well as pull; and the rollers R R" may have a positive motion imparted to them so as to assist in feeding the clayr down.

` We claim as new, and of our inventionv 1. In the described combination the hopper B, travelling bottom E, rollers C, D, and F, throatv H, and shaver or knife G, for the purpose set forth.

2. The compressing rollers N N', when combined with the trunk composed of the two endless aprons Q Q', rollers R R', and back-boards S S.

3. The combination of trunk Qv Q', R R', S S', and conducting and separating throat T, U, u.

4. The described combination of separating throat T, U, u, reciprocating knife 9, and removable moulds 3.

5. The endless carrier Y Y', Z z, 1, when combined with the reciprocating hooks or claws 5, substantially as described.

In testimony of which invention we hereunto set our hands.
